### 4. Functionality
Operating Principle:
The W‑M2B301 functions as a remote digital input node on an RS‑485 Modbus/RTU network. A host controller (PLC, PAC, or PC) polls the module using Modbus commands to read input states, counters, or latch registers. Each input channel can detect either contact closures (dry mode) or voltage signals (wet mode). The module’s microcontroller debounces and filters input transitions, ensuring reliable detection even in electrically noisy environments.
Use Cases and Applications:
- Industrial process monitoring and control
- Machine status and alarm input collection
- Energy management and power distribution monitoring
- Building automation and security systems
- Laboratory and test automation
- Remote telemetry and SCADA data acquisition
- Direct digital control (DDC) and facility management systems
Compatibility:
Fully compatible with standard Modbus/RTU masters and software platforms such as SCADA, LabVIEW, Ignition, Citect, and custom PLC programs. The module can coexist with other Wolf‑series analog or digital modules on the same RS‑485 bus.
